How to perform Xpath looping?

Question

While working on selenium,I have the xpath

//tbody[@id='se-tbody-result']//tr[3]//a

I want to loop tr[value] from tr[3] to tr[20].

Answer 1

Such xPath would return you values from tr[3] til tr[20]

//tbody[@id='se-tbody-result']//tr[position()>=3 and position()<=20]//a
